Architecture Design of Distributed Real-Time Simulation System

Research on distributed simulation and design a distribtuted simulation architecture.Depending on the requirements of real-time simulation, first a kind of real-time operation system(rtos) is needed,and then real-time communication is need to be researched.Through design and experimentation,RTX rtos and reflection memory communication meet the requirements.Based on the real-time simulation? architecture,a common simulation platform is designed and used in the control system tests,improves simulation performance.
